Hey there. Trying to figure out how to find a hall voltage across a ribbon. I'm given J, B, and some other factor: R-sub-h OHM*meter/tesla. (no clue what this is... )I'm also told to assume the charge carriers are e-'s. I understand that the hall effect is used to determine which charges are actually moving, but i can't really understand how the hall voltage is determined outside of V(hall) = q*width of ribbon*B. I'm really not looking for an answer, but some general guidelines or tools that will help me solve the problem. Thanks in advance.
